So from the front page of VG Chartz:

"Remote Play has been popular for people who own a PLayStation 4 and PlayStation Vita. However, that will shift the focus of the Vita from a AAA handheld system to an add-on for the PlayStation 4. So the focus of the handheld may be shifting."
When was the last time Sony viewed Vita as an AAA system at all? I think it's basically their way of saying yeah, we're not making any more Vita games for the Western market.
